Union of 2 Squares: How Many Regions Can Mike Get?

In summary, the Union of 2 Squares problem involves drawing two squares and connecting all of their corners with lines to determine the number of regions in the resulting shape. The number of regions can be calculated using the formula (n^2 + n + 2)/2, where n is the number of corners in the shape. This problem is significant as it introduces students to various mathematical concepts and has real-life applications. There is a general solution for the problem, but there are also different methods and variations that can make it more challenging and introduce new concepts.

The correct answer would be (D) 8. This can be determined by using the formula for the maximum number of regions that can be formed by n intersecting lines or curves, which is (n^2 + n + 2)/2. In this case, n=2 since there are two squares, so the maximum number of regions would be (2^2 + 2 + 2)/2 = 8. This can also be visually determined by drawing the two squares and counting the number of distinct regions formed.
